HERBERT H. DREW, OF WATERLOO, WISCONSIN.

STANCHION.'

Specification of Letters Patent.

Patented Dec. 26, 1916.

Application filed April 21, 1916. Serial No. 92,593.

To all whom it may concern:

Be it known that l, HERBERT H. DREW, a citizen of the United States, and resident et' iilaterloo, in the county ot' Jeii'erson and State ot 'Wisconsin have invented certain new and useful improvements in Stanchions; and I do hereby declare that the Afollowing is a full, clear, and eXact description thereof.

The present invention is directed to new and useful improvements in cattle stanchions, more particularly of that type wherein the upper ends of the neck bars are both mounted for opposite sliding movement to procure a maximum opening movement of the stanchion and to reduce the space between both neck bars and the adjacent steering post when the stanchion is open.

It is in general the object of the present invention to improve the structure and efficiency of devices of this character, particularly with respect to providing a maximum degree and readiness of adjustment of the neck bars, it being more specifically an object to provide for the retention of a free pivotal movement of the neck bars about their points of attachment, to permit a maximum freedom of movement to a cow confined in the stanchion, and further wherein upon movement of the cow either forwardly or baclrwardly the stanchion will positively grip the cow in a manner tending to discourage such movement.

It is further an object of the invention to so simplify the entire general structure of the stanchion as to promote economy in manufacture, and a ready assembly ofthe stanchion in operative position, and further to provide for maintaining a sanitary condition of the stanchion structure.

ln the drawings: Figure 1 is an elevational view ot a pair of stanchions constructed in accordance with the present invention. Fig. 2 is a fragmentary top plan view of the upper guide bars of the stanchion and showing the locking plate for the stanchion.

Referring now more particularly to the accompanying drawings, 5 designates a plurality of stall posts extending from the bed i6 of a manger and the upper ends of these posts are flattened as at 7, to provide for 'the securement thereto of a pair of guide 'bars 8 formed preferably of angle-iron and having their vertical sides opposed to form a guide channel for the upper ends of the pairs ot stanchion bars 9 and 10, each of these bars being similar in structure with the exception that the latch plate hereinafter to be described is permanently connected with the upper end of the bar 9. The general structure of each bar comprises a pipe section 11 having a cushioning member l2 secured to its inner face and fitted in the bottom of the pipe section is a rod 13 having its lower portion bent inwardly at an obtuse angle with its extremity bent outwardly at an acute angle and this eX- tremity is engageable in one of a series of openings 15 formed in the web portion of a channel shaped base bar 17 mounted on the manger bed 6. rlhe pipe is held from turning movement with respect to the rod 13 by an open slot 16 in its bottom portion which receives the lower end of the rod. At the upper end of the pipe section a rod 17 is fitted thereinto which has its upper portion also directed inwardly at an cbt-use angle with its extremity bent again at an obtuse angle to extend into the guide channel formed by the bars 8, the upper end of the pipe being also provided with an open slot 18 preventing relative rotation with respect to the bar 17. The extremities 14; of the bottom rods 13 provide a universally pivotal mounting of the stanchion bars.

whereby the bars may swing toward and away from each other and the bars are limited in their swinging movement apart by stop bolts 19 passed through the guide bars 8. The bars are also prevented from swinging inwardly past the central position by a stop bolt 19, passed through the guide bars, and thus when the neck bars are connected they are held in a substantially vertical position.

A latch plate 20 is provided for securing the bars together in operative position and this plate is permanently connected with the stanchion bar 9 by passing the upper end of the portion 17 of said bar through one of a series of apertures 21 formed in the plate, a suitable cotter or other stop member 22 being carried by the extremity of the bars. The plate is provided with depending flange portions 23 at its sides which embrace the channel bars 19, and thus the plate is slidably held in alinement with the path of movement of the stanchion bars. For automatically locking the stanchion bar l0 to the plate upon moving it in conjunction therewith, the adjacent end of the plate is upwardly inclined to provide a cam surface and inwardly of this cam surface is provided an opening 24 adapted to receive the upper extremity of the portion 17 ot' this stanchion bar,` possible movement of this upper extremity inwardly of the opening being prevented by a lug 25 depending from the plate intermediately inwardly of the opening. It is noted that the extremity of the portion 17 of the stanchion 9 is longer than the similar portion of the stanchion 10 and thus the plate may retain its proper seating on the bars 8 while permitting full swinging movement of the stanchion 9 to an open position.

Inasmueh as both of the neck bars are movable, the space between each neck bar at its adjacent stall postl in open position of the stanchion, is lessened to such an extent that a cow would have no tendency to insert its head therein, particularly inasmuch as this arrangement also procures a relatively greater distance between the neck bars in their open position. Thus the provision ot' means such as a chain for directing a cows head between the neck bars is obviated. Inasmuch as the pivotal connections of the neck bars are disposed inwardly of the body portions of the bars, the bars would permit a slight swinging movement of the cows head. Movement either torwardly or backwardly, however, would swing the bars on their pivots, and thus the bars would press into a cow either in forward or backward movement and would effectively discourage tendency to such movement.

I claim:

1. A stanchion comprising a base plate provided with a series of openings, a p air of neck bars having their lower end portions directed inwardly with their eXtremities directed outwardly, and engageable selectively in the openings, and means for adjustably securing the upper ends of the bars together.

2. A stanehion comprising a pair of neck bars, means for pivotally securing the lower ends of the bars, a guide channel for the upper ends of the bars, and a latch plate carried by the upper end of one bar and having its end adjacent the other bar upwardly inclined and provided with an opening inwardly of said inclined portion.

A stanchion comprising a pair of neck bars, means pivotally securing the lower ends of said bars, a latch plate provided with a series of openingsreceiving the upper end of one of said bars, the end of the plate adjacent the other bar being inclined upwardly and provided with an opening inwardly oft said inclined portion and a stop on the plate inwardly of the opening.

i. A stanchion comprising a pair of neck bars, means pivotally securing the lower ends oit the neck bars, a pair of horizontally disposed guide bars forming a channel receiving the upper ends of the neck bars, a latch plate having depending portions embracing the channel bars, and provided with an opening, the end ol one neck bar extending above the other neck bar and passed through said opening, and the end of the latch plate adjacent the said other neck bar being inclined upwardly and provided with an opening inwardly of said inclined portion.

5. A stanchion comprising a pair of neck bars each comprising a body pipe section having an open longitudinal slot in each end portion, a pad carried at one side of the pipe section, an angular lower pivot rod itted in the lower end of the pipe and having a portion extending through the slot to prevent relative rotation ot the pipe member, an angular rod engaged in the Vupper end of the pipe member and having a portion extending through the slot to prevent relative rotation, means for pivotally securing the lower rods, means for guiding the upper rods and a latch means for securing said upper rods together.

In testimony that I claim the foregoing I have hereunto set my hand at Edgerton, in the county of Rock and State of Wisconsin.
